9 Claims.

This invention relates to improvements in manifolding device.

The main objects of this invention are:

First, to provide a manifolding device or apparatus which may be readily incorporated in existing types of typewriting machines primarily for the purpose of facilitating the manipulation of multiple webs in association with carbon sheets.

Second, to provide a manifolding apparatus or device in which the carbon sheets are assembled as a pack and may be quickly interleaved or interspaced with the paper and supported so that the paper may be manipulated in relation to the carbon sheets in a manner greatly expediting the work.

Third, to provide a means for releasabl supporting a carbon pack in operative relation to the paper and the platen which is highly effective and at the same time quickly operated to secure or release the carbon sheets.

Fourth, to provide a device having these advantages which is very compact and economical in structure and may be readily embodied in the form of an attachment to be applied to type writing machines now in extensive use. I

Objects pertaining to details and economies of the invention will appear from the description to follow. The invention is defined in the claims.

A structure embodying the features of the invention is clearly illustrated in the accompanying drawing, in which:

Fig. 1 is a fragmentary perspective View of a typewriting machine embodying my invention, the machine proper being illustrated conventionally and in more or less skeletonized form.

Fig. 2 is a perspective view of the carbon pack and web guide device of my invention embodied as an attachment for a machine of the type illustrated.

Fig. 3 is an enlarged fragmentary view partially in longitudinal section on a line corresponding to line 3-3 of Fig. 4.

Fig. 4 is an enlarged fragmentary vertical section on a line corresponding to line 4-4 of Fig. 1 including the platen of the typewriting machine.

Fig. 5 is a fragmentary view partially in section corresponding to Fig. 3 showing the carbon pack clamp in open position, it being shown in closed position in Fig. 3.

Fig. 6 is a fragmentary perspective view of the rockshaft and one of the clamping rollers.

Fig. '7 is a fragmentary perspective view of the carbon pack illustrating its relation to the multlply paper webs, a part of the carbon sheets being folded back to illustrate that they are free at one edge.

Fig. 8 is an enlarged fragmentary view in section on line 88 of Fig. 7.

In the accompanying drawing i represents a typewriting machine. 2 is the platen of the machine and 3 the guide and supporting rollers for the webs of paper 4. As the structural details of the machine form no part of my invention and as my invention is capable of adaptation or em bodiment in various types of machines, I do not illustrate or describe the details of the machine herein.

In the embodiment of the invention illustrated I provide an auxiliary frame designated generally by the numeral 5 and adapted to be mounted on the carriage frame of the typewriting machine. The auxiliary frame comprises end members 6, 6, a front cross bar or member 1, and a rear cross bar or member 8. The end members are provided with supporting backets 9 having thumb screws Ill by means of which the auxiliary frame is mounted on the cross bar or member ll of the carriage frame. The end members 6 of the auxiliary frame are downwardly offset at l2 so that the front member 1 is positioned above and fairly close to the platen.

The front member 1 constitutes a clamping bar or member for the carbon pack and is desirably a flat piece disposed vertically edgewise. On the inner side of the member I I mount a rockshaft l3, the journals 14 of which are eccentrically disposed as shown in Fig. 5. The rockshaft is provided with a crank l5 at its right hand end by means of which the rockshaft may be rotated and thereby swung to and from the clamping member I as clearly shown in Figs. 3 and 5. The parts are in actuated position in Fig. 3 and in retracted position in Fig. 5. A stop It is provided to limit the forward stroke of the lever which is the retracting stroke.

The rockshaft is provided with a pair of clamping members designated generally by the numeral l1. In this preferred embodiment these clamping members are in the form of resilient rollers l8 rotatably mounted on the sleeves is between the flanges 20 of the sleeves and the retaining collar 2|. The sleeves are fixed to the rockshaft, at least anchored against longitudinal movement thereon.

I provide a carbon pack designated generally by the numeral 22 which consists of a.plurality of carbon sheets 23 having laterally projecting integral tabs 24 and 25 on their side edges. The tabs 24 are bound together by means of the ilexiof paper. The pack may .be easily adjusted longitudinally of the webs of paper into proper position to permit clamping of the binding tab of the pack and also the free tabs into proper relation for clamping between the clamping rolls and the clamping bar. The resilient rotatable clamping members I! are highly desirable .because they minimize the liability of tearing or injuring the carbon pack. With the carbon pack suitably clamped in operative relation to the platen as shown "in Fig. '4 the webs of paper may be pulled or fed through the plies of the carbon pack in mani fold relation as it will be noted that the carbon pack is 'clampingly supported laterally of the edges of the webs. The carbon pack is secured in its adjusted position and may be relased simply by shifting the handpiece it. With the clamp members released the carbon pack may be rolled in manifold relation with the webs of paper to any desired position on the platen.

The rear cross member 8 of the auxiliary frame serves as a guiding support for the multiple webs of paper and is provided with adjustable guide members 29 slidable on the member 8 and secured in adjusted positions by the thumb screws 30.1

The guide members have fingers ti which overlap the Webs of paper. This guiding means is effective-in keeping the webs of paper in proper lateral position in the machine and may be adjusted to accommodate paper of different widths.

In the drawing the carbon pack is illustrated l as positioned in the machine with the tabs on the leading end thereof. It may be positioned in the manner illustrated or invertedthat is, positioned with the tabsat the lower edge'of the pack. This arrangement has the advantage of lessening the possibility of wrinkling the sheets of the pack held by the tabs when the forms are pulled through as friction then tends to straighten out the carbon sheets and to maintain them in proper position without wrinkling and without special care in manipulation of the paper webs.

'I have illustrated and described my invention in a highly practical embodiment thereof. I have not attempted to illustrate or describe various l modifications and adaptations which I contemplate as it is believed that this disclosure will enable those skilled in the art to embody or adapt the invention as may be desired.
